At a late meeting of the British Association (1862), Pro 

 fessor Owen read a paper e On the brain and limb characters 

 of the Gorilla as contrasted with those of Man,' * in which, 

 without alluding to the disclaimer by the Dutch anatomists 

 of their defective plates, now so widely circulated in Eng 

 land, he observes, that in the gorilla the cerebrum ' extends 

 over the cerebellum, not beyond it.' This statement, although 

 slightly at variance with one published the year before 

 (1861) by Professor Huxley, who maintains that it does pro 

 ject beyond, is interesting as correcting the description of the 

 same brain given by Professor Owen in that year, in a 

 lecture to the Eoyal Institution, in which a considerable part 

 of the cerebellum of the gorilla was represented as uncovered.! 

 In the same memoir, it is remarked, that in the Maimon 

 Baboon the cerebrum not only covers but f extends backwards 

 even beyond the cerebellum.' J This baboon, therefore, 

 possesses a posterior lobe, according to every description 

 yet given of such a lobe, including a new definition of the 

 same lately proposed by Professor Owen. For the posterior 

 lobe was formerly considered to be that part of the cerebrum 

 which covers the cerebellum, whereas Professor Owen defines 

 it as that part which covers the posterior third of the cere 

 bellum, and extends beyond it. 



We may, therefore, consider the attempt to distinguish 

 the brain of Man from that of the ape on the ground of 

 newly-discovered cerebral characters, presenting differences 

 in kind, as virtually abandoned by its originator, and if the
